Well grown microtubes of Ba3Ce3-xBixTi5Nb5O30 (x = 0.5, 1.0, 2.0, and 3.0) have been observed in the sintered ceramics. The microtubes have octagonal shapes at the cylindrical ends, hollow cores with diameters of 2-3 mu ...

Physico-chemical transformations of ZnO have been investigated in low temperature reflux reactions involving zinc nitrate, arious ZnO micro/nano structures were systematically examined from 4 to 60 h. The study showed ...

Surface aligned, uni-directionally grown, hexagonal nanorod bundles and microrod pillared arrays of zinc oxide (ZnO), were synthesized through a simple, homo-epitaxial growth approach. A uniform layer of ZnO seed was ...

We report the photoluminescence properties of a novel powellite-based red-emitting phosphor material: CaLa1−xNbMoO8:xEu3+ (0.01, 0.03, 0.05, 0.1) for the first time. The photoluminescence investigations indicated that ...

The present work investigates the dielectric properties of pyrochlore type oxides, Ca-Sm-Ti-M-O (M = Nb and Ta) in the low frequency region (100 Hz-1 MHz) over the temperature range 30-100 A degrees C. The 1 MHz dielectric ...
